"CABLE OR WIRE PLASTIC SECURING DEVICE Filed Oct 17, 1966 I N VENTOR ATTORNEY United States Patent 3,341,651 CABLE OR WIRE PLASTIC SECURING DEVICE John Odegaard, 5618 8th Ave.,

. Brooklyn, N.Y. 11220 Filed Oct. 17, 1966, Ser. No. 587,261 2 Claims. (Cl. 174-159) ABSTRACT OF THE DISCLOSURE A stand-off insulator for a flat or round cable formed initially as a straight bar of flexible and bendable plastic material having on one face thereof a central rectilinear depression flanked at each end with a semi-circular depression and a cylindrical opening at each end of the bar provided with an annular flange adjacent the opposite face of the bar. Provided on the opposite face of the bar are finger receiving depressions. A supporting spike to which the insulator is connected has at its rear end a neck and tapered head. In the connection of the insulator to the spike, the tapered head is inserted through the opening at one end of the insulator with the flange seated in the neck. The insulator is then bent into U-shape and the tapered head inserted through the other opening such that both flanges are in abutting engagement and held within the neck of the spike. The rectilinear depression is then somewhat arcuate and is adapted to clampingly engage a flat cable while the semi-circular depressions are in opposed relation to clampingly engage a round cable.

This invention relates to a stand-off insulator cable or wire securing device.

The principal object of this invention is to provide a stand-off bar insulator formed of a flexible and/ or bendable plastic material initially of rectilinear elongated shape and symmetrically profiled on one face thereof with pairs of correspondingly shaped depressions and openings such that when the bar is bent into U-shape about its center the correspondingly shaped depressions and openings will be brought into opposed relation with the depressions varying in size and shape to receive selected different sizes and shapes of cables or wires to be clamped therebetween when the legs of the bent bar are brought together on the head of a fastener and supporting spike extending through the opposed openings and driven into a wall or other supporting surface.

Another object of this invention is to provide on the other face of the bendable plastic bar pairs of like symmetrically arranged depressions providing when the bar is bent into U-shape finger holds to facilitate handling of the stand-off cable securing device.

A still further object of this invention is to provide a stand-off cable securing device which is supported by the head of a fastener and supporting spike and which completely masks such spike from view.

Yet another object of this invention is to provide a stand-off cable securing device that is of extreme simplicity, easy to manufacture and of low cost, simple to apply to a cable or wire and to mount on a wall by the use of a single fastener spike, which is extremely durable and which cannot become accidently disengaged over prolonged periods of time.

Further objects of the invention will appear as the description proceeds.

To the accomplishment of the above and related objects, my invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that change may be made in the specific construction illustrated and described within the scope of the appended claims.

FIGURE 2 is a cross-sectional view taken on line 2-2, FIGURE 1.

FIGURE 3 is a side elevational view of the fastener and supporting spike.

FIGURE 4 is a perspective view showing the securing device applied to a cable and the manner of securing the same to the fastener spike.

FIGURE 5 is a plan view of the securing device as used in FIGURE 4.

FIGURE 6 is a similar view showing the securing device with a different type of cable.

FIGURE 7 is a similar view showing the securing device with yet another different type of cable.

FIGURE 8 is a detail sectional view taken on line 8-8, FIGURE 5.

Referring to the drawing, the stand-off cable securing device 10 is shown in FIGURE 1 in its initial bar form of rectilinear elongated formation and is made of a suitable flexible and bendable plastic material, preferably polyethylene, possessing high insulating properties. The bar 10 has a flat outer face 12, a profiled inner face 14, and parallel sides 16, 17. Each end of the bar 10 is rounded as at 18, 20.

Formed in the profiled inner face 14 of the bar 10 is a central flat depression 22 flanked on each end thereof by an arcuate depression 24, 26. Adjacent each of the rounded ends 18, 20 of the bar 10 are respectively, openings 28, 30. The openings 28, 30 each have respectively a flanged bottom wall 32, 34 at the inner face 14 defining respectively reduced diameter openings 28a and 30a, for a purpose to be hereinafter described.

Formed in the flat outer face 12 of the bar 10 are pairs of depressions 36, 38 with the depressions 36 deeper than the depressions 38 and disposed adjacent the openings 28, 30. As seen in FIGURES l and 2, the depressions 22, 24, 26, 36, 38 and openings 28, 28a and 30, 3011 are symmetrical about the medial transverse center axis A-A of the bar, see FIGURE 1.

FIGURE 5 illustrates the manner of utilizing bar 10 as a cable securing device. Inserted through the opening 28, 28a of the bar 10, see FIGURES 1 and 2, is a fastening and supporting spike 40 similar to that shown in my prior Patent No. 2,527,442, granted Oct. 24, 1950. The spike 40, of elongated tapered shape is made of metal, one side 41 being straight while the other side 42 is notched as at 43 in order to prevent the easy removal of the spike when it is driven into a mortar joint or concrete wall as shown in FIGURE 5. The head portion 45 of the spike 40 is tapered at its terminal end as at 46 and is provided with opposed recesses 48, 49 adjacent to the tapered end 46 defining a neck 50. Thus, on inserting the spike 40 through opening 28, 28a the bottom flange 32 is forced into encircling relationship to the neck 50' to provide a positive support of the end 18 of the bar 10 on the spike.

After the spike 40 with attached bar 10 is driven into the concrete wall 52 to a predetermined position, the bar 10 is then bent into U-shape about the transverse axis A-A to receive in recess 22 a cable 54, it being noted that the portions of the inner face 14 on each side of the transverse axis AA are brought into opposed contacting relationship such as to clampingly confine the cable 54 within the recess 22 which becomes arcuate in form. When so bent into U-shape the opposite end 20 of the bar 10 will have its opening 30a opposite the spike head 45 such that by tapping the end 20 with a hammer as. shown in FIGURE 4, the tapered head 45 will be forced through opening 30a in bottom flange 34 into the opening 30 with the bottom flange encircling the neck 50 and in abutting engagement with the bottom flange 32, see FIGURE 8. Thus, the stand-off securing device provided by the bar when bent into U-shape is not only positively connected and/or attached to the'spike 40 but also is securely clamped to the cable54. It will be noted that the head 45 of the spike 40 is fully contained within the opening 30 making for an attractive and uniform support and connection for the cable 54. a

In order to facilitate the bending and holding of the bar 10 in its connection to the spike head and cable, the depressions 36, 38 provide finger engaging recesses.

FIGURE 6 illustrates the stand-off securing device clamped to a modified form of cable 56 which seats in recesses 24, 26, which in FIGURE 7 a still further modified form of cable 58 is shown clamped in recess 22.

While certain novel features of my invention have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing from the spirit of the invention.
